# Styling and CSS

The direktiv-ui project has two approaches to styling components and pages. Below is a simplified version of this repository files in a tree view that we'll use throughout this document.

<div className="subheading">Tree view of project</div>

```
/
├── Dockerfile
├── ...
└── src
    ├── App.css
    ├── App.js
    ├── components
    │   ├── button
    │   │   └── index.tsx
    │   ├── ...
    │   └── flexbox
    │       ├── index.tsx
    │       └── style.css
    ├── index.css
    ├── index.js
    ├── layouts
    │   ├── ...
    │   └── events
    │       ├── index.js
    │       └── style.css
    ├── ...
    └── theme
        └── style.tsx
```

<div className="subheading">APP Wide CSS</div>

Before we continue onto the styling approaches, it's important to note that App-wide styling classes and variables are defined in `src/App.css`.

```
/
├── Dockerfile
├── ...
└── src
    ├── **App.css**
    ├── App.js
    ├── ...
    └── theme
        └── style.tsx
```

<div className="subheading">Approach 1 - style.css</div>

When navigating the component and layout directories you will notice some of them contain a `style.css` file bundled alongside their TSX/JSX file. These CSS files plus the App.css are whats used to style the React Nodes in their directories.

Below are some examples of this approach seen in the flexbox component at `src/components/flexbox/style.css` and the events layout at `src/layouts/events/style.css`.

```
/
├── Dockerfile
├── ...
└── src
    ├── App.css
    ├── App.js
    ├── components
    │   ├── button
    │   │   └── index.tsx
    │   ├── ...
    │   └── flexbox
    │       ├── index.tsx
    │       └── **style.css**
    ├── index.css
    ├── index.js
    ├── layouts
    │   ├── ...
    │   └── events
    │       ├── index.js
    │       └── **style.css**
    ├── ...
    └── theme
        └── style.tsx
```

<div className="subheading">Approach 2 - MUI Theme Provider</div>

While approach 1 has served well since the start of this project, recently there has been an effort to switch to a UI library to make this project's styling be more consistent and maintainable as it scales in complexity.

For this reason, MUI was added to this project with its ThemeProvider wrapping the entire App. Only a handful of JSX/TSX elements make use of MUI currently, below is highlighted a component that uses MUI `src/components/button/index.tsx`.
The MUI theme can be found at `src/theme/style.tsx`.

```
/
├── Dockerfile
├── ...
└── src
    ├── App.css
    ├── App.js
    ├── components
    │   ├── button
    │   │   └── **index.tsx**
    │   ├── ...
    │   └── flexbox
    │       ├── index.tsx
    │       └── style.css
    ├── index.css
    ├── index.js
    ├── layouts
    │   ├── ...
    │   └── events
    │       ├── index.js
    │       └── style.css
    ├── ...
    └── theme
        └── **style.tsx**
```
